Geomagnetic Storm Hits Earth

I've never seen the lights before so it was an experience I'll never forget.

Also, as a note, there seemed to be some kind of "magnetic pole" just south of the center point in the sky (overhead). It was like there were "waves" that were blown from the northern horizon, and the "waves" trickled across the sky and converted into a single distinct point. That point was like a warped magnetic point, not unlike a shadow cast by shining light through the bottom of a clear injection molded plastic ball. It was very cool. I'm curious if that's a common trait of the northern lights?
